FOUNTAIN PAIN T-BRUSH.

Specification of Letters Patent.

Application iiled September 23, 1911.

Patented May 14, 1912.

Serial No. 650,945.

T0 all 'whom t may concern.'

Be it known that I, TETsUsAURo WATA- NABE, a subject of the Emperor of Japan, residing at New York, in the county of New York and State of New York, have invented a certain new and useful Improvement in Fountain Paint-Brushes, of which the following is a specification.

The invention is a fountain paint brush, and comprises a brush, stock, a paint reservoir thereon, a downwardly contracting tube leading the paint from said reservoir to the bristles in the stock, and means operated by the wiping motion of the brush in applying paint, for causing a flow of said paint from the reservoir to the bristles.

The construction is such that while the brush is not in use, no air can get into the reservoir, which is preferably in the handle, and hence there is practically no leakage therefrom; but as soon as the brush is operated, then a rod which extends through the lower opening of the delivery tube is swung to and fro to permit air to enter the reservoir, and also to keep said opening free.

The term bristles hereinafter used, includes any hair, fiber, wire, or other material, in common use for brush making.

In the accompanying drawings-Figure 1 is a side elevation, and Fig. 2 is a longitudinal section of my fountain paint brush.

Similar numbers of reference indicate like parts.

l is the circular stock, in which the bristles 2 are secured in any suitable way. In said stock is a central opening in which is the funnel-shaped delivery tube 3. Supported in lugs t, 5 on the upper side of the stock and diametrically across the tube 3 is a bar 6, from which is suspended the rod 7 which passes through the contracted lower opening of tube 3 and extends for a distance below said opening. One of the lugs, as 5, may be of spring metal, so that it can be retracted, as shown in dotted lines Fig. 2, to allow of the removal of the journals on the endsof bar 6 from both lugs, to permit withdrawal of rod 7 from tube 3. On the upper side of stock 1 is an internally threaded rim Hange 8, with which engages the externally threaded flange 9 on the hollow handle 10. At the extremity of the handle is a screw plug 11.

In operation, the handle is adjusted in place on the stock, the screw plug 11 is removed, and the handle is filled with liquid paint. Screw plug 11 yis then replaced. The brush is then used in the ordinary way. As the bristles wipe over the surface to be covered, the protruding end of rod 7 is moved from side to side, thus swinging the rod 7 in the opening at the end of tube 3. This causes the paint to flow from tube to bristles, since the effect is both to admit air to the reservoir and to keep the opening free, so that the outflow of paint to the brush is gradual and continues as long as the rod 7 is kept in motion. When the brush is not in use, practically no air can enter the handle, and hence the paint flow ceases.

I claim:

1. A paint brush, comprising a stock for bristles, a paint reservoir carried thereby having an open funnel-shaped extension and connecting with said bristles, and means in said extension operable by the wiping motion of the brush in applying paint, for maintaining a free passage for paint through said eXtension to said bristles.

2. A paint brush, comprising a circular stock for bristles, an open centrally disposed funnel-shaped tube depending therefrom and surrounded by said bristles, a rod supported on said stock and extending across said tube, a rod suspended from said first-named rod,

4passing through said tube and extending beyond the same, and a paint reservoir on said stock and communicating with said tube.

In testimony whereof I have affixed my signature .in presence of two witnesses.
